First, the two hollow panels (60) and (70) in the butted state are placed and fixed on the base (92), and then the probe (82) of the welding tool (80) is rotated while rotating the probe (82). ) Is inserted into the butting portion (90) of the upper outer plate portions (61) and (71) from the front side thereof. Normally, insertion is performed until the shoulder (81a) of the rotor (81) comes into contact with the surface of the upper outer plate (61) (71) as shown in FIG. Then, with the probe (82) inserted and the shoulder (81a) of the rotor (81) pressed against the surface of the upper outer plate (61) (71), the probe (82) is joined to the butt. Move relatively along (90). As the probe (82) moves, the vicinity of the contact portion with the probe (82) is softened and agitated sequentially by frictional heat, and the softened and agitated portion rapidly loses the frictional heat and is cooled and solidified. The upper outer plate portions (61) and (71) of the hollow panels (60) and (70) are joined and integrated at the butting portion (90).

The two hollow panels (60 ') and (70') shown in FIG. 3 are formed by end faces of upper outer plate portions (61 ') and (71') and lower outer plate portions (62 ').
With the end faces of (72 ') abutting each other, a gap (92') is formed between opposing outermost ribs (63a ') and (73a').

い。That is, when the probe (82) is inserted into the butting portion (90 '), as shown in FIG. 2B, the insertion pressure of the probe (82) and the shoulder (81a) of the rotor (81) are increased. Due to the pressing pressure, both ends of the upper outer plate portion (61 ') (71') are pushed inward, and the butting portion (90 ') is opened inward. Thus, the butt (9
0 ') is opened, the upper outer plate (6
Since 1 ') and (71') are joined, the joining state becomes poor. Further, even when the butting portion (90 ') is not opened and both ends of the upper outer plate portion (61') (71 ') are maintained in the butting state, the butting portion (90') is not closed. Since a gap (92 ') is formed on the back side, this gap (92')
The softened portion softened by the frictional heat flows out into the inside, so that it is not possible to obtain a butt joint having a good joined state.

い。In order to prevent the outflow of the softened portion, a backing (not shown) may be brought into contact with the back surface of the butted portion (90 '). However, since the insertion pressure of the probe (82) and the pressing pressure of the shoulder (81a) of the rotor (81) are also applied to this backing, the backing receives these pressures and receives the upper outer plate (61 '). ) And (71 ') are pushed inward together with (71'), and as a result, good bonding cannot be performed.

In the case of (70), both ends of the upper outer plate portions (61) and (71) are supported by the outermost ribs (63a) and (73a). Both ends are not pushed inward, and the outer surfaces of the outermost ribs (63a) (73a) are in contact with and in close contact with each other, so the softened portion softened by frictional heat Does not leak out.

る。In order to achieve the above-mentioned object, the present invention provides a method for manufacturing a vehicle, comprising the steps of:
2 connected by a plurality of ribs arranged at intervals
Pieces of the hollow panel-shaped joining members are arranged so that the plate-like bodies are abutted so that the outermost ribs face each other and a gap is formed therebetween, and the abutting portion is frictionally stirred from the outside in the thickness direction. A butt joint structure formed by joining
In the gap, the backing portion connected to one joining member is brought into contact with the back surface of the plate-shaped body of the other joining member in a manner of straddling the butt portion, and the back surface of the backing portion is
It is characterized in that friction stir welding is performed in this state by abutting and supporting a supporting portion connected to the other joining member.

高品位なものとなる。According to this, the backing portion connected to one of the joining members is brought into contact with the back surface of the plate-like body of the other joining member so as to straddle the butt portion, so that the backing portion is softened by frictional heat. It is possible to prevent the softened portion from flowing out into the gap. Then, the back surface of the backing portion is brought into contact with and supported by a support portion provided continuously with the other joining member, thereby maintaining the contact state between the backing portion and the back surface of the plate-shaped body of the other joining member. And it is possible to reliably prevent the softened portion from flowing into the gap, and to prevent the butting portion from being opened due to the probe insertion pressure and the rotor pressing force. Can be. Therefore, the friction stir welding is performed satisfactorily without causing poor joining, and the butt joint thus obtained has a good joining state and high quality.
